[0024] FIG. 1 is a block diagram of an electronic device for performing an integrated monitoring method for an RTU-based sewer pipe manhole pump according to one embodiment of the present invention.

[0025] Referring to FIG. 1, an electronic device (100) for performing an integrated monitoring method for an RTU-based sewer pipe manhole pump according to one embodiment of the present invention may be configured to include at least one processor (110), a memory (120), and a transmitting / receiving device (130).

[0026] For example, at least one processor (110) may mean a central processing unit (CPU), a graphics processing unit (GPU), or a dedicated processor on which methods according to embodiments of the present invention are performed. Each of the memory (120) and the storage device (160) may be composed of at least one of a volatile storage medium and a non-volatile storage medium. For example, the memory (120) may be one of read-only memory (ROM) and random access memory (RAM), and the storage device (160) may be a flash memory, a hard disk drive (HDD), a solid-state drive (SSD), or various memory cards (e.g., a micro SD card).

[0027] Additionally, the transceiver (130) can communicate via a wireless network, and each component included in the electronic device (100) can communicate with each other by being connected by a bus (170).

[0028] For example, the memory (120) can store at least one instruction performed by the processor (110), and at least one instruction can be executed to perform at least some operation of the integrated monitoring method for the RTU-based sewer manhole pump described below.

[0030] FIG. 2 is a diagram showing terminals performing an integrated monitoring method for an RTU-based sewer pipe manhole pump according to an embodiment of the present invention.

[0031] Referring to FIG. 2, a server (210) that performs an integrated monitoring method for an RTU-based sewer pipe manhole pump according to one embodiment of the present invention may be represented as an integrated monitoring server and may represent the electronic device (100) of FIG. 1, but is not limited thereto. For example, the server (210) may transmit and receive information via wired or wireless communication with an RTU (220) corresponding to a manhole pump of a sewer pipe and a user terminal (230) capable of checking the status information of the manhole pump collected through the RTU.

[0032] For example, the RTU (220, Remote Terminal Unit) may represent a device that collects data from a remote location, converts the data into a transmittable format, and transmits it. In this case, it may sense or collect information regarding a sewer pipe or a manhole pump in a sewer pipe and transmit the data to a server (210) or a user terminal (230). As the definition or function of the RTU itself is obvious to a person skilled in the art, a detailed description is omitted in this specification. For example, the RTU (220) may be connected to or include a first sensor that measures the voltage and current of the manhole pump and a second sensor that measures the water level of the manhole pump, and the first sensor may be divided into a sensor that measures voltage and a sensor that measures current. Additionally, the RTU (220) may be connected to or include a third sensor that measures the insulation resistance of the manhole pump, and may be further connected to or include a control module that controls the operation of the manhole pump.

[0033] For example, the user terminal (230) may be a communicable desktop computer, laptop computer, notebook, smartphone, tablet PC, mobile phone, smart watch, smart glass, digital camera, digital video recorder, digital video player, PDA (Personal Digital Assistant), etc., but is not limited thereto, and may include all computing electronic devices.

[0036] FIG. 3 is a conceptual diagram illustrating an integrated monitoring method for an RTU-based sewer pipe manhole pump according to one embodiment of the present invention.

[0037] Referring to FIG. 3, an integrated monitoring method according to one embodiment of the present invention can be performed through data acquisition, pump condition analysis, fault prediction, data processing, and data transmission processes.

[0038] For example, in the case of data acquisition, the electronic device may acquire data through an RTU corresponding to a manhole pump in a sewer pipe, and the RTU may be connected to or included in an AD converter corresponding to the manhole pump to perform data acquisition. Here, the acquired data may include at least one of the voltage of the manhole pump, the current of the manhole pump, the ultrasonic water level of the sewer pipe, and the insulation resistance of the manhole pump, and each data may be sensed through individual sensors for data acquisition, and a single sensor may acquire multiple data, or a single data may be acquired through multiple sensors. That is, in one embodiment, the current and voltage of the manhole pump may be measured through a first sensor, the ultrasonic water level may be sensed through a second sensor, and the insulation resistance may be sensed through a third sensor, but each sensor may be implemented as a single sensor or divided into multiple sensors.

[0039] For example, in the case of pump condition analysis, the electronic device can estimate the RPM of the manhole pump based on acquired data, and may also utilize the manhole pump's specification information at this time. In addition, the electronic device can predict the flow rate or discharge volume of the manhole pump based on the estimated RPM and acquired water level information.

[0040] For example, in the case of fault prediction, the electronic device can generate status information of the manhole pump through sensed data and estimated / predicted RPM and discharge volume, thereby detecting the state of the manhole pump and predicting whether it is currently in a faulty state or if it is deviating from normal operation and will soon fail.

[0041] For example, in the case of data processing, the electronic device may use RAM among storage devices for the analysis described above and may store the analyzed data in flash memory among storage devices, but analysis and storage may be performed using various storage devices, and is not limited thereto.

[0042] For example, in the case of data transmission, the electronic device can provide the analyzed and stored data to the user by transmitting it to the display of the user terminal, or it can transmit the analyzed and stored data to a separate server.

[0044] FIG. 4 is a conceptual diagram illustrating a method for estimating the flow rate of a manhole pump according to one embodiment of the present invention.

[0045] Referring to Fig. 4, the electronic device can first estimate the RPM of the manhole pump to predict the flow rate of the manhole pump. For example, the electronic device can estimate the RPM through a pump induction motor sensorless algorithm based on the induction motor circle diagram, and at this time, the sensed voltage / current and the specification information of the manhole pump can be used.

[0046] In addition, the electronic device can derive effective suction head information from water level information through structural analysis by considering the structure based on the specification information of the manhole pump, estimate flow rate information according to the effective suction water information based on the efficiency of the manhole pump, and the efficiency of the manhole pump can be determined based on the specification information of the manhole pump.

[0048] FIG. 5 is a flowchart of an integrated monitoring method for an RTU-based sewer pipe manhole pump according to one embodiment of the present invention.

[0049] Referring to FIG. 5, in operation S510, the server can obtain voltage information and current information of the manhole pump from the RTU, and in operation S520, the server can obtain water level information of the manhole pump from the RTU. To this end, the RTU can be connected to a first sensor that measures the voltage and current of the manhole pump and a second sensor that measures the water level of the manhole pump so that the above-described operation can be performed.

[0050] In operation S530, the server can estimate the RPM information of the manhole pump based on voltage information, current information, and specification information of the manhole pump, and in operation S540, the flow rate of the manhole pump can be estimated based on RPM information and water level information. For example, the server can derive effective suction head information based on water level information, and can estimate the flow rate based on RPM information and effective suction head information. In other words, the server can estimate what RPM the sensed voltage and current have through the specification information of the manhole pump, obtain structural information of the manhole pump through the specification information, derive effective suction water information through the structural information and water level information, and thereby estimate flow rate information, i.e., discharge amount information.

[0051] In the S550 operation, the server can provide status information of the manhole pump, including RPM information, water level information, and flow rate information, to the user terminal.

[0052] For example, the server may obtain insulation resistance information of a manhole pump from the RTU and may generate information regarding the presence or absence of an abnormality in the manhole pump based on the insulation resistance information. In this case, the RTU may be connected to a third sensor that senses insulation resistance, and the status information provided to the user terminal may further include insulation resistance information and information regarding the presence or absence of an abnormality in the manhole pump.

[0053] Alternatively, for example, the RTU may be further connected to a control module that controls the operation of the manhole pump. In this case, the server may obtain control information from the user terminal based on one of RPM, water level, or flow rate based on status information, generate control information for the manhole pump based on the control information, and transmit the control information to the RTU so that the manhole pump is controlled according to the control information from the user terminal. Alternatively, if the current water level based on the sensed water level information exceeds a preset threshold water level without separate control information from the user terminal, the server may generate acceleration control information to accelerate the operation of the manhole pump, and transmit the acceleration control information to the RTU so that the manhole pump is controlled automatically.

[0056] The operation according to the embodiments of this specification may be implemented as a computer-readable program or code on a computer-readable recording medium. A computer-readable recording medium includes all types of recording devices in which data that can be read by a computer system is stored. Additionally, a computer-readable recording medium may be distributed across networked computer systems, allowing computer-readable programs or code to be stored and executed in a distributed manner.

[0057] When the embodiment is implemented in software, the above-described technique may be implemented as a module (process, function, etc.) that performs the above-described function. The module may be stored in memory and executed by a processor. The memory may be located inside or outside the processor and may be connected to the processor by various well-known means.

[0058] In addition, computer-readable recording media may include hardware devices specifically configured to store and execute program instructions, such as ROM, RAM, and flash memory. Program instructions may include machine code, such as that generated by a compiler, as well as high-level language code that can be executed by a computer using an interpreter, etc.

Similarly, aspects described in the context of a method may also be described according to a corresponding block or item or a feature of a corresponding device.
